Sounds for Laughing/Giggling/Chuckling

[salix_catus]

There should be a sounds for laughing giggling and chuckling. this would make things funnier (duh).
Imagine... a Sec officer can hear lots of giggling nearby and it turns out to be....

• the janitor smoking a joint with the bartender
  
• N2O
  
• The clown playing with a dead monkey's eyes
  
• A traitor after spacing a body

I think it'd be a welcome addition to the station's ambience of screaming farting and honking.
